_transient_random_seed Question

Hello.

I'm using a plugin called Paranoid911 since I was recently hacked and the plugin updates me about changes to my database and files. It sent me an email today that the option:

_transient_random_seed

was changed. So I quickly deleted it but then realized that maybe that was stupid.

I googled for it and can't find what "_transient_random_seed" is used for.

Any ideas?

Thanks,
Giovanni
